Much more important to the character are the internal scars, with the act of killing his father weighing heavily on him during the course of The Last Jedi, with Adam Driver saying:
"I feel like almost everyone is in that rehabilitation state. You know, I don’t think that patricide is all that it’s cracked up to be. Maybe that’s where Kylo Ren is starting from. His external scar is probably as much an internal one.”
